[求助] 请高手帮忙翻译个句子

The diurnal evaporative emissions measurement enclosure shall be equipped with an internal blower or blowers coupled with an air temperature management system (typically air to water heat exchangers and associated programmable temperature controls) to provide for air mixing and temperature control. The blower(s) shall provide a nominal total flow rate of 0.8 ± 0.2 ft3/min per ft3 of the nominal enclosure volume, Vn. The inlets and outlets of the air circulation blower(s) shall be configured to provide a well-dispersed air circulation pattern that produces effective internal mixing and avoids significant temperature or hydrocarbon and alcohol stratification. The discharge and intake air diffusers in the enclosure shall be configured and adjusted to eliminate localized high air velocities which could produce non-representative heat transfer rates between the engine fuel tank(s) and the air in the enclosure. The air circulation blower(s), plus any additional blowers if required, shall maintain a homogeneous mixture of air within the enclosure.

昼夜蒸发排放测量箱需要配备一个内置风机或连接温度管理系统(较为典型的是空气至水的热交换器及相关的可编程温度控制器)的多个风机,以便提供空气混合和温度控制功能。风机应提供每ft3标准测量箱体积Vn0.8±0.2 ft3/min的总额定流量。空气循环风机的入口和出口的配置应提供合理分布的空气循环模式,产生有效的内部混合,避免显著的温度差异或碳氢化合物和酒精的分层。测量箱的排气和进气的配置应消除局部的高空气流速,(因为)后者会导致不具代表性的发动机油箱和测量箱内空气之间的热传递率。空气循环风机及其他所需的附加风机应在测量箱中维持均匀的空气混合。
